9000btu split

[Draco]

hi guys,
i have a 9000btu split unit returned to me by a customer, the unit ran for a while it seems, customer complaint not pumping.

when i opened the unit it seems the compressor got hot due to stickers melted on compressor, when i turn on the unit, the compressor makes a loud buzzing noise then kicks out but does not trip the board, the fan still works, when i turn the unit off, you can hear a click from the compressor.

what could cause this to happen to the compressor apart from over heating? insufficient gas, too much gas or liquid in th system?

Cheap compressor, running without or not enough refrigerant, bad elactrical connections, air in the system.

The click is the overload on the compressor.
